The error indicates that the objects are relatively not centered and cannot be cyclically (mutually) dependent. My layout file is written as follows:

............

<Linearlayout
Android: Id = "@ + ID/linearlayout_line"
Android: layout_width = "fill_parent"
Android: layout_height = "1dip"
Android: layout_below = "@ ID/tl_title"
Android: Background = "@ color/gray">
</Linearlayout>

<Linearlayout Android: Id = "@ + ID/linearlayout_person"
Android: layout_width = "fill_parent" Android: layout_height = "fill_parent"
Android: layout_below = "@ ID/linearlayout_line" Android: Background = "# ffffff">

<Listview Android: Id = "@ + ID/listview_person"
Android: layout_width = "fill_parent" Android: layout_height = "wrap_content"
Android: cachecolorhint = "@ null">
</Listview>
</Linearlayout>

<Linearlayout Android: Id = "@ + ID/linearlayout_line"
Android: layout_width = "fill_parent" Android: layout_height = "5dip"
Android: layout_below = "@ ID/linearlayout_person" Android: Background = "@ color/button_bg">
</Linearlayout>

..........

Take a closer look at the layout file, there are two views with the ID of linearlayout_line. The view for Android: Id = "@ + ID/linearlayout_person" sets layout_below = "@ ID/linearlayout_line ", the bottom Android: Id = "@ + ID/linearlayout_line" sets layout_below = "@ ID/linearlayout_person". Obviously, this layout is impossible, view1 is set at the bottom of view2 and view2 at the bottom of view1, which is obviously impossible if the dependency similar to the loop is in the layout file. Therefore, you only need to set the following Android: Id = "@ + ID/linearlayout_line" to Android: Id = "@ + ID/linearlayout_line11.
